I have a weakness for keeping these old ladies original as possible, looking at your model - it looks like you have less work laid out finding parts as it all seem to be there. Here is a pick how the bike looked when I bought it and two after I restored it. I honestly spend very little money getting it to look nice, a lot of polishing / buffing and time. Had to find side covers (non modified) airbox, carbs and exhaust. Rebuild carbs, new gaskets new oil tires and seat cover plus a few other rubber / plastic parts. Was lucky to get a brand NOS gas tank among a bunch of parts and bikes I bought, otherwise no new paint or chrome - all cleaned up.
The previous owner had plans of making a cafe racer - I feel lucky to have spoiled that attempt.
Unfortunately you are almost as far north as I’m south on the east coast otherwise I would have entertained the idea of helping it off your hands or trade you for another ‘75 have sitting around however with quiet a few missing original parts
. Good luck whatever you do - did I mention “ nice find”
